Wei Hong on "Error on second redirect"

Hi,

My site was hacked last week and I engaged sucuri service to fix the malware issues. But after that my site is running very slow and right now have a serious issue on redirecting the page.

Here is the scenario,

If I directly key in the URL as http://www.prforaustralia.com/en/testimonial >> the page will be able to load.

however, if I key in the home directory http://www.prforaustralia.com/en and then I click on the menu bar to direct to another place. I am unable to load the page "testimonial".

Anyone have any idea how to fix this?

Thanks.
